Question

What is the product of Bromo Blue, CaCl2 (calcuim cloride) and NaHCO3 (baking soda)?

Answer 1

Bromo Blue is green in near neutral solutions, and turn yellow in weak acid solutions.

So the question what is a solution of CaCl2? neutral to very slightly alkaline
NaHCO3? slightly basic

So I would expect greenish blue from BromoBlue.
